After completing the autopsy on Friday afternoon, Dr Sohail Mahmud, head of the forensic department at Dhaka Medical College, said she died due to excessive bleeding in her vaginal and anal areas.
Samples were also collected for DNA profiling, as well as to determine whether any anaesthetic drug was administered to Anushka prior to death.
Dr Sohail added that the exact cause of death could only be ascertained once the autopsy report is out.
Earlier, evidence necessary to determine her precise age was also collected. Later, the body was handed over to her family who would be taking it to Kushtia for burial.

Death penalty for rape ineffectual?
The government last November amended the law changing the maximum penalty for rape to death. The death penalty was already stipulated for incidents of rape followed by murder.
Even after the law was changed on October 1, 2020 some 160 incidents of rape were reported in the country till December 31, according to advocacy group Ain O Salish Kendra (ASK), suggesting the provision of death penalty may have no practical effect on deterring sexual violence against women.

Last year, 1,627 women became a victim of rape. Fifty-three of them were killed after rape and 14 of the victims took their own lives, according to ASK. The actual number is believed to be higher as many victims choose not to report assaults fearing their safety.
